By now, some of you would probably have read from Mitchell Baker or David Ascher about the re-integration of Mozilla Messaging. It will be combined with Mozilla Labs, and Mozilla Messaging will be dissolved.
David will continue to manage the Thunderbird team along with the various other responsibilities wrt. the Labs stuff, F1, Raindrop, contacts, identity and the like. As he puts it, “Thunderbird users will likely be curious to know what this change means for them. The short answer is almost nothing will change.”
“In particular, the Thunderbird team will remain a tight-knit self-contained product team with full responsibility for the stewardship, development and support of Thunderbird.”
